Insert for metric internal threads with a pitch of 3.5 mm
The 16 IR 3.5 ISO BMA threadinginsert is an effective threading tool. It produces metric fine internal right-hand thread s with a pitch of 3.5 mm on the lathe. ISO standard and full 60-degree profile ensure dimensional compliance.
Supports M30, M33 and other metric threads with 3.5mm pitch. Mounting in an external toolholder converts the tool to a left-hand insert. You will machine materials such as steel, aluminum and cast iron without problems. BMA carbide has exceptional hardness and toughness. The tool for medium and larger holes in industrial structures.
Key advantages of 16 IR 3.5 mm ISO BMA insert
- High-hardnessBMA carbide provides durability in intensive use
- Solid profile dedicated to 3.5 mm pitch guarantees ideal thread geometry
- Bi-directional use as inner right or outer left insert
- Resistance to wear in the harsh conditions of structural steel machining
Tool used in lathe hole threading in heavy construction production. Machinery industry, steel construction, equipment repair are the main applications. Manufacturing workshops appreciate the reliability and dimensional repeatability of the BMA insert. Choose a proven solution for fine threads of medium and large diameters. Invest in a tool that can withstand the demands of intensive industrial production.

Frequently asked questions
1. Which threads does the 16 IR 3.5 ISO BMA insert support?
The insert is designed for fine internal metric threads with a pitch of 3.5 mm. The 60-degree solid profile corresponds to the ISO standard . The range includes M30, M33. Any metric thread with this specific pitch can be made.
2. How to use the insert for external machining?
Mounting in a suitable holder transforms the insert into an external left-hand tool. The setup geometry and angle must be precisely adjusted. Flexibility of use increases the value of the tool in a versatile workshop. One blade supports different threading configurations on the lathe.
3. What is the height of the turned thread outline for this insert?
H1 - Height of thread outline given in mm || P - pitch of thread given in mm
H1 = 0.54127 * P
For this pitch is: H1 = 0.54127 * 3.5 mm = 1.89 mm
